I am retired person and frequently buy and sell shares in the market through NSE through broker. While I did make profit in trading I have suffered capital erosion because of market price crashing. The difference between sales turn over and purchase turn over is below Rs.40 lakhs and my holdings are worth around Rs.25 L based on market price. Please confirm whether I need to maintain accounts / share audit etc. I have nett basis incurred loss only because of capital erosion. I have also paid huge S.T.T. because of purchase/sales. Can you kindly clarify. I am a middle class person.
